Benefits of technology

The present invention minimizes the time required to provide a digital TV application when switching channels. This is done by dividing the application into minimum and additional execution data, and only receiving and executing the necessary information. Additionally, the size and number of the digital TV application are also minimized. The application can also be personalized based on device or user identification information.

Problems solved by technology

Therefore, a number of the digital TV application is limited, and a size and a configuration the digital TV application are also limited.
That is, because the digital TV application is transmitted using a limited resource, the number of and the configuration of the digital TV application are limited.
Therefore, a personalized digital TV application cannot be provided for the viewer.
Moreover, a long time is required from selecting of the digital TV application to loading of the digital TV application.
When the packet is lost during the transmission, the digital TV application cannot be executed for some cases.
However, the digital TV application cannot be executed when a portion of the packets thereof is lost.
Therefore, an execution speed is slow and a resource of the receiver is excessively used.
Due to above-described problems, the time required for receiving, executing and providing the digital TV application is 10 to 30 seconds.
Therefore, it is very inconvenient for the viewer.
Therefore, it is very inconvenient for the viewer.
Moreover, the execution of the digital TV application is limited by a processing capacity or a storage capacity of the receiver.
That is, when a size of the digital TV application is too large, the digital TV application cannot be executed.
Therefore, the number of and the configuration of the digital TV application are limited.

Embodiment Construction

[0058]A method for switching a digital TV application in accordance with the present invention will now be described in detail with reference to the accompanied drawings.

[0059]FIG. 1 is a flow diagram exemplifying a method for switching a digital TV application in accordance with the present invention wherein the method is embodied in a receiver for receiving and executing the digital TV application.

[0060]Referring to FIG. 1, a channel changing event is received (S110).

[0061]The channel changing event is generated when a viewer or a user changes a first channel to a second channel while watching the first channel. When the channel changing event is generated, the receiver receives the digital TV application for the second channel and provides the received digital TV application to the user.

[0062]For instance, the channel changing event is generated when the user changes the channel using a remote controller, and the receiver receives the channel changing event from the remote contro...
